RIYADH/DOHA (Reuters) -U.S. President Donald Trump was wrapping up his Gulf tour on Friday having secured what the White House says is over $2 trillion for the U.S. economy in combined deals. The trip included big orders of Boeing planes, deals to buy U.S. defence equipment, data and technology agreements and other contracts. Of the corporate agreements worth up to $549 billion during the Trump's Gulf tour, many were non-binding memorandums of understanding, according to a Reuters analysis.
